Playground dynamics

Scenario

A school counselor administers a sociometric survey to a class and maps the results to identify social stars, isolates, and conflict pairs. The force-directed layout naturally clusters tight friendship groups and surfaces bridging individuals — the counselor can immediately see who is at social risk and which cross-group connections are worth nurturing.

Annotation key

• group id [label:..., color:...] — defines a named group; members listed below with ; separator
• <-> — mutual/reciprocal choice (both children named each other)
• -> — one-way positive nomination (A chose B, B did not choose A)
• -x> — conflict or rejection edge; rendered with an X marker
• -.- — neutral / weak tie; neither positive nor negative nomination
• config: layout = force-directed — uses physics simulation to position nodes; tightly connected nodes cluster naturally
• config: coloring = group — colors each node by its assigned group

How to read

The diagram shows two tight cliques: the blue boys' group (Tom–Jack mutual friendship, with Leo drifting at the edge) and the red girls' group (Anna–Beth–Chloe triangle). Leo and Mike have a conflict edge — an immediate flag for the counselor. Diana sits between groups with only a weak tie to Tom, suggesting social isolation risk. Anna has the most outward nominations, making her a social star worth engaging as a peer ally.
